FURNACE.

Patented Mar. 2, 1915..

Application filed February 24, 1914. Serial No. 820,627.

To all whom it may concern:

Be it'known that we, WILLIAM S. LINooLN and JAMES F. WHrr'r, citizens of the United States of America, residing at "Nickerson,

, in the county of Reno and State of 'Kansas,

which may be made easily portable or stav tionary to accomplish the desired results, and which consists of a mlnimum number of parts.

Vith these and other objects in view this. invention conslsts of certain novel combinations, constructions,and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a detail perspective of the furnace. Fig. 2 is acentral vertical section therethrough. Fig. 3 is a transverse section taken on line 3-3, of Fig. 2. Fig. 4 is a vertical section taken on line 4,4-, of Fig. 2. Fig. 5 is a transverse section taken through the rear supporting brace which carries the band or tire supporting brackets. Fig. 6 is a detail perspective of one of the tire supporting brackets. Fig. 7 is a detail perspective of the door used in connection with the present invention. Fig. 8 is an end view of" the furnace showing the latch mechanism which is adapted to hold the door in a closed position.

Referring to the drawings it will be seen that 1 designates the body of the furnace which comprises a substantially rectangular frame, and this frame tapers toward its upper end to constitute a reduced tapered neck 2 terminating in a discharge funnel 3, which funnel is mounted upon the reduced end 2 of the body 1 as is illustrated in Figs. 1 and 2. The body 1 comprises aplurality of angle iron corner pieces 4 over which corner pieces are placed the sheet metal plates 5 going to make up the outer casing or shell of the furnace.

A plurality ofangle irons6 are carried by the front and rear walls of, the outer shell and these angle irons 6.constitute sup porting bars or ribs for supporting the grate bars 7, which grate bars extend transversely of the furnace as is clearly illustrated in Figs. 2, 3 andt.

Art inner wall 8 is spaced from the rear wall of the body 1 as is illustrated in Fig. 3, and has its side edges engaging the rear angle irons 4 going to make up the frame of r the furnace. A central. vertically extending'channel iron 9 is carried by the body 1 and extends Vertically therein, and is spaced between the inner wall 8 and the rear plate of the body 1 of the furnace. Studs 10 pass through the wall 8 and through the rear Wall of the body 1 and constitute efficient means for holding the inner plate 8 in firmengagement with the body of the furnace. The rear wall 8 extends approximately one-half the height of the body 1, as is illustrated in Fig. 2 to constitutea protector against the fire adapted to be mounted upon the transversely extending grate bars 7 of the furnace 1. Inner walls 11 are carried by the ends of the body and arespaced therefrom by means of the corner angle irons 1 and the projecting flanges 12 formed upon the rear plate 8. Transversely extending studs 13 through the walls 11 and'body 1 for firmly holding the walls '11 in engagementwith the I body'l.

A door llis hingedly secured to the body 1 by means of hinges l5, and a latch bar 16 is fixedly secured to the outer face of the door, which latch bar 16 is adapted to fit in the. keeper 17 for holding the door 14: in a closed position. The door lt comprises an outer plate 18, which plate is provided with a substantially inverted V-shaped frame 19 extending along the upper edge thereof, and this flange 19 is preferably formed of angle iron as is illustrated in Fig. 7. An inner plate or wall 20 is carried near the lower end of the door 14 and is firmly held in engagement with the door by means of the transversely extending rivets 21 as is illustrated in Figs. 8 and 7 By carefully considering Fig. 8 it will be seen that the furnace comprises an inner the outer plate 18 of the door 14; it will be seen that a draft can easily pass up between lower end of this angle iron 23.

A plurality .of substantially V-shaped hook or band supporting brackets 24 are mounted'upon the centrally located channel iron 9, and these brackets are provided with the laterally extending substantially U- shaped feet 25, which fit over the flange portion 26 of the channel iron 9. Rivets 27 pass through the feet of the brackets 24: for firmly holding the same in engagement with the channel iron 9. These channel irons 9 are riveted or otherwisesecurely fastened to thebody lof the furnace. It should be understood that by means of the substantially Ul-shaped feet of thebrackets that the same will be greater reinforced and relieveconsiderableof the lateral strain of the brackets when placing the hooks or bands 28 upon the brackets 24 as illustrated clearly in Figs. 2 and it.

Itshould be understood that by means ofthe present furnace, tires or bands may be very quickly heated, and at the same time very evenly heated, for the purposeof obtaining the fullestv expansion possible with- V out burning the wheel or other object upon which the band or Wheel or tire is adapted to be placed. It should be further understood that owing to the peculiar shape of thefurnace, considerable fuel will be saved in view of the fact that the heated gases Will be forced upwardly and Will be forced to rise closely to the pieces or hooks to be heated. It should be further understood Copies of this patent inay be obtained for five cents each, by addressing the that owing to the fact that the furnace is provided With the inner shell spaced from thereby cause an efficient upward draft and cause 'the burnt gases to be directed upwardly and in this manner more eiiiciently heat the articles placed within the furnace. It should be understood that the sloping or inclined sides will constitute a deflector for the flames against the upper part of the tire .or band, thereby allowing the band to be efliciently heated.

By means of the present construction it will be seen that the furnace by being open at the bottom and top will insure a free circulation of cool air through the channel between the inner and outer casings, thereby keeping the outer shell or casing cooler than is possible in a closed air space. It should be further understood that owing to this particular construction the device may be very easily repaired, and it should be further understood that any form of material, as above stated, may be used for heating the furnace.

Having thus described the invention what is claimed, as new, is

In a device of the class described, a body portion, inner and outer casings, a central vertically extending channel iron, a plurality of substantially V shaped supporting brackets mounted upon said channel iron, said supporting brackets provided with laterally extending substantially U shaped feet and constituting support for bands adapted to be placed thereon.

In testimony whereof we hereunto aflix our signatures in presence of two witnesses.
